Answer:
The 5th bullet under Rule PH 22 was inadvertently omitted. A corrected version of the Heme manual will be posted soon. Thank you for identifying this omission.
In the meantime, please add the following to PH22:
Code the primary site to lymph nodes, NOS (C779) when lymph node(s) are involved but no primary site/particular lymph node region is identified.
